This is something that matters as well though choice of games mentioned in the OP do provide guidance that might make the Glock a solid choice. Works for lots of really killer shooters.
Almost all the time you hear some dude online rambling about it's the shooter/guitarist/driver/rider/photographer not the gun/gear/car/bike/camera and lens and then you go on to see they have a $5000 pair of STI's, Gibson and Mesa, 911, $30k Panigale, or $20k in glass. Tools matter. The same people parroting "indian not the arrow" won't shoot a match with a Sigma will they? PT1911 instead of an STI? Hell, if we're talking M&P 1.0 in 9mm the gun might not even be capable of an A-zone hit. Sure as shit the gear matters. How much is the trick. Fortunately things balance out to where the G17/34 or VP9 will be just fine.
